How can I know the number of qubits used in a job in qiskit?
I can always do something like
retrieve_job = provider.backend.retrieve_job(job_id) retrieve_job.circuits()[i].draw(),
i is the ith-circuit. However, if I have a large number of circuits in a job, I don't want to check manually which qubits my circuit used (I am sure that before the transpilation I never use all of the qubits).
ibmq_something, but I may be wrong in that the method exists. $\endgroup$
